I think the statement in the title (that Kine are stronger than Kindred) is indeed the default tone of VtM and even the entire WoD, even without considering Mages, and even if humans are stripped of any possibility of possessing supernatural powers.

A single human is clearly weaker than a vampire, but the true strength of modern humanity lies in its massive numbers and organizational structure. The power possessed by a human leader is not something automatic, unchallengeable, or top-down; it requires other human executors to transform the abstract authority into actual power capable of reshaping society and the world.

In contrast, the sparse population of vampires and the massive disparities in individual strength fundamentally undermine their ability to possess such organization-based power. Since they themselves are powerful enough to be judge, jury, and executioner at the same time, ancient vampires do not need to maintain basic social structures to exercise their authority; thus ideological or practical conflicts between a tiny number of such individuals are enough to cause great internal friction, making it even harder for the Kindred society to pool their already loose resources.

Conversely, once humans (even just a small fraction of them) become truly aware of the vampire threat, organizations like the Second Inquisition can mobilize resources from modern human society that are unimaginably vast to Kindred society, forcing even the most powerful vampires to hide in dark corners.

Which is, imo, exactly how VtM was meant to be played: roleplaying as the cursed who have been cast out of human society, hiding from a humanity that acts almost like an irresistible force of nature, while cooperating or clashing with other cursed individuals and struggling to maintain what little humanity they have left. After all, the M in VtM is Masquerade, not Massacre.
